A 17-year-old boy presented with fatigue, hypoxia, palpitations, and anemia (hemoglobin 3.5 g/dL). The search for the etiology of the bleeding began with a Meckel scan. A photopenic region in the gastric body and a region of abnormal tracer uptake in the right midabdomen were unexpected findings. Further investigation with ultrasound and computed tomography revealed a gastric mass, which proved to be a gastrointestinal stromal tumor at pathology. The right-sided tracer uptake resulted from stasis in the collecting system of a malpositioned right kidney, a cause of false uptake in a Meckel scan.

Intussusception in adult patient is rare. Gastroduodenal intussusception due to the gastrointestinal stromal tumors is infrequently described in the literature. Authors present a case of gastroduodena...
Peritoneal tumor penetration (PP) strongly affects prognosis in gastrointestinal carcinomas. In gastrointestinal stromal tumor (GIST), its significance in the absence of tumor rupture has not been sub...
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract; most of them have gain-of-function mutations of the KIT gene. There have been rare cases o...
Meckel's diverticulum, a congenital malformation of the gastrointestinal tract, is asymptomatic in the majority of patients but can be associated with some complications. Gastrointestinal bleeding is ...
The purpose of this study was to investigate the computed tomography (CT) features of 2-5 cm gastric gastrointestinal stromal tumors (GISTs), schwannomas and leimyomas which have close relationship ...

Comparison of Endoscopic and Laparoscopic Resection for Small Gastric Gastrointestinal Stromal Tumor
Gastrointestinal stromal tumor (GIST) is the most common non-epithelial mesenchymal tumor of the gastrointestinal tract. Surgical treatment is the only curative therapy for primary localiz...
A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).
Neoplasms derived from the primitive sex cord or gonadal stromal cells of the embryonic GONADS. They are classified by their presumed histogenesis and differentiation. From the sex cord, there are SERTOLI CELL TUMOR and GRANULOSA CELL TUMOR; from the gonadal stroma, LEYDIG CELL TUMOR and THECOMA. These tumors may be identified in either the OVARY or the TESTIS.
Drugs used for their effects on the gastrointestinal system, as to control gastric acidity, regulate gastrointestinal motility and water flow, and improve digestion.
A proto-oncogene protein and member of the Wnt family of proteins. It is frequently up-regulated in human GASTRIC CANCER and is a tumor marker (TUMOR MARKERS, BIOLOGICAL) of gastric and COLORECTAL CANCER.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
